再生水水面浮床种植草坪草的研究

[目的]设计一种适合草坪草生长的浮床。[方法]在不施肥不灌溉条件下,在再生水水面上浮床种植3种草坪草:高羊茅、草地早熟禾、匍匐翦股颖,进行浮床种植试验。[结果]结果表明:利用泡沫板作为漂浮载体,上铺无纺布作为基质在再生水水面上种植的3种草坪草均能正常生长;水面栽培条件下高羊茅的叶绿素含量、叶片含水量、干重、密度、盖度等指标均显著高于土培。[结论]葡茎翦股颖和高羊茅较草地早熟禾更适宜水面浮板无土栽培。

Study on Cultivation Turfgrass Application of Floating-beds on Reclaimed Water Body

[Objective]The aim of this paper was to design one kind of the floating bed suitable for the cultibation of turfgrass.[Method] Three kinds of turfgrasses(Festuca arundinacea,Poa pratensis,Agrostis stolonifera) were cultivated on reclaimed water surface on the floating beds without fertilization and irrigation.[Result] Three kinds of turfgrass could grow well with foam plate as a vector floating,capped cloth as a matrix in the surface of regenerated water.For under-water cultivation,F.arundinacea chlorophyll content,water content,dry weight,density,cover rate and other indicators were significantly higher than those under soil culture conditions.[Conclusion] A.stolonifera and F.arundinacea was more suitable to the under-water cultivation than kentucky bluegrass.
